ELECTRIC-MOTOR SUPPORT.

SPECIFICATION forming part of Letters Patent No. 415,070, dated November 12, 1889.

Application filed January 26, 1889. erial No. 297,665 (No model.)

To all whom it ntay concern.-

Be it known that I, SIDNEY H. SHORT, of Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Improvement in Electric-Motor Supports; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to an electric motor, and particularly to the construction and arrangement of the parts supporting the same upon the truck of the car whichit is designed to propel.

The object of the invention is to provide a simple supporting-frame for the motor, which, while connected with the car-axle, relieves it of the direct weight of the motor, this weight being taken up by the truck-frame, which is usually spring-supported, and to .provide also an intermediate spring and insulating support between the truck-frame and the motor.

In the drawings, Figure 1 is a side elevation of. a car-truck, showing my motors in posit-ion, one at each end. Fig. 2 is a side ele- Vation, enlarged, of the motor and its support. Fig. 3' is a plan view of the same. Fig. 4 is a front elevation. Fig. 5 is a plan view of the lower frame-work of the truck.

In these figures the car-wheels are shown at A, having their bearings in suitable boxes 13 of ordinary construction, and through flanges on these boxes pass rods 0. 01,, which connect the upper and lower longitudinal bars a b of between the upper bars 0; on eachs de and the flanges of the boxes, which thus give a cushioning effect between the axle and the body of the car. Between the lower horizontal bars I) 011 each side, which are preferably made of channel-iron, I extend crossbars 0 c, which serve as the direct support, through an interposed cushion of rubber e, for the frame supporting the motor. The motorframe consists of side bars e e, the ends of which are hub-shaped and divided, so as to be held to the axle of the car, as shown in Figs. 2 and 3; but the connection is not rigid, but forms a pivotal connection for the said frame. The side bars of the motor-frame are connected about their center by strengthening-webs, which are enlarged at the outer edge Coiled springs are interposed on each side to form hearings in which is journaled a shaft 0, upon one end of which is a wheel driven directly from the motor and upon the other end a driving-gear in direct connection with a wheel fast to the axle of the car and through which connection the car is driven. The side walls at the front of the frame are extended above and below to form supports for the fields and the shaft of the armature, as shown in Fig. 4. The two side walls are connected beneath the motor by a girder, which is'provided at its center with a socket f, which is fitted to the upper part of the rubber or other suitable flexible cushion resting upon the cross-bar c. This forms a spring and insulating bearing directly beneath the center of the motor, the greatest amount of the motors weight being supported at this point and the axle of the car thus being relieved. A similar motor,supported in' like manner, is arranged at the opposite end of the car, as shown in Fig. 1, for imparting motion to the other axle. It will thus be seen that both motors are practically independent of each other; that they are each supported by a spring cushion, which in turn is supported by the spring-supported car-truck. The parts are properly insulated, suitable insulation being provided between the caraxles and the motor-frame, and the connection between the driving-gear on the motorshaft and the large Wheel on the countershaft may be an insulated one by interposing insulation between the teeth of the gears or by making the teeth of insulating material.

It will be understood that while I have shown the motors as supported directly beneath their centers at one point, I do not desire to be limited in this respect, as two buffers or cushions can be provided, one being placed beneath the motor at each end thereof instead of in the center.

I claim as my invention- 1. In combination with the truck of a car and the axles thereof, a motor supported between the side walls of a frame, said frame IOO porting said motor between its side walls at one end, said frame having a rear extension pivoted to the axle of the car, driving-connections between the motor and the car-axle carried by the frame, a cross-bar connecting the longitudinal bars of the truck beneath the motor, and a cushion between said crossbar and the frame of the motor, substantially as described.

3). In combination, a motor, a frame having supports for the same at one end, and having a rear extension to the axle of the car, insulated therefrom, a spring-supported truck, a cross-bar connecting the lower longitudinal bars of the said truck, a connecting-girder bcneath the motor, extending between the side walls of the frame, and an insulator-cushion supported on the crossbar directly beneath the center of the motor, substantially as described.

4. In combination, a motor, a frame having supports for the same at one end and having a rear extension to the axle of the car, a spring insulator-cushion between the motor and the truck of the car, and a counter-shaft carried by the frame of the motor and adapted to communicate motion from the motor to the car-axle, substantially as described.

5. In combination with the truck of a car, a motor for each axle, having an insulatorcushion between each motor and truck, and driving-connections from the motor to the axle, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two sub- 35 scribing witnesses.
